In an antenna feed structure for electrically connecting a rotatable antenna to a circuit formed on a circuit board by means of a feeding metallic part, an antenna rotary shaft formed so as to protrude from one end of the antenna and formed of a conductor has a preferably spherical end. The feeding metallic part has a mounting portion, an antenna contact-and-connection portion, and an elastic supporting portion. The mounting portion is mounted to the circuit board. The antenna contact-and-connection portion is brought into contact with and is connected to the end of the antenna rotary shaft. The elastic supporting portion supports the antenna contact-and-connection portion at the mounting portion and produces biasing force towards the antenna rotary shaft from the antenna contact-and-connection portion. The antenna contact-and-connection portion has a recess wall preferably having a spherical shape which is in correspondence with the spherical shape of the end of the antenna rotary shaft. The spherical end of the antenna rotary shaft press-contacts the spherical recess wall of the antenna contact-and-connection portion.
